vecdelay is similar to vdelay, but it works at k-rate and, instead of delaying a single signal, it delays a vector. ifnIn is the input vector of signals, ifn is the output vector of signals, and ifnDel is a vector containing delay times for each element, expressed in seconds. Elements of ifnDel can be updated at k-rate. Each single delay can be different from that of the other elements, and can vary at k-rate. imaxdel sets the maximum delay allowed for all elements of ifnDel.
